Raveena Tondon and Anupam Kher will be seen sharing screen space after 13 years in "Alert" and the actress is all praise for the actor's sense of humour.

"Loved working with Anupam Kher again after years, still retains amazing ability of keeping everyone in splits with his wicked sense of humour, " Raveena wrote on her Twitter page.

"Still remember 'Parampara', it was very difficult to keep from laughing out loud even in serious scenes, with Anupam around... 'Zamana Deewana' too, " she added.

Both of them also worked in "Ladla" and they were last seen in 1998 film "Bade Miyan Chote Miyan".

Anupam wrote on his Twitter page: "Worked with Sanjay Dutt and Raveena Tandon after a long time. It felt good. Their warmth was heart warming."
